Validity Checks

There 3 possible validity checks > https://docs.gitlab.com/user/application_security/vulnerabilities/validity_check/#validity-check-workflow

Request Query	UI Text
validityCheck=UNKNOWN	"Possibly active secret"
validityCheck=ACTIVE	"Active secret"
validityCheck=INACTIVE	"Inactive secret"

How to set up and validate locally

1. Enable FF: http://gdk.test:3000/rails/features/advanced_vulnerability_management
2. Enable FF: http://gdk.test:3000/rails/features/validity_check_es_filter
3. Enable FF: http://gdk.test:3000/rails/features/validity_checks_security_finding_status
4. Enable FF: http://gdk.test:3000/rails/features/validity_checks
5. Clone this project: https://gitlab.com/gitlab-org/govern/threat-insights-demos/frontend/validity-checks/-/security/vulnerability_report/
6. Run a successful pipeline
7. Go to the vulnerability report page
8. Filter by validity token
9. In the network request, you'll see validityCheck being passed as an argument
10. 🚨 Because the BE is still WIP, the report does not return the filtered result.
